SPECIFICATION forming part of Letters Patent No. 519,260, dated May 1,189 Application filed May 2 1, 1892. SerialNo. 4345379. (No model.)

To all whom it may concern.-

Be it known that I, JOHN K. HUNTER, a citizen of theUnited States ofAmerica,residing at Owensborough, in the county of Daviess and State ofKentucky, have invented certain new and useful Improvements in Slidesfor Sewing-Machines, of which thefollowing is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to improvements in slides for sewing machines, andit consists in the construction and arrangement of parts which will befullydescribed hereinafter and particularly pointed out in the claims.

The object of my invention is to provide a slide for sewing machines,which can be pushed or snapped in position in contra-distinction tosliding the same, and which will not become loose from wear and be movedby the jar of the machine. In the accompanying drawings: Figure 1, 1s aninverted perspective view of a slide for rotary shuttle machines whichembodies my invention. Fig. 2, is a transverse sectional view of thesame showing itin position. Fig. 3, is an inverted perspective view of aslide for reciprocating shuttle machines. Fig. .4, is a view showing theslide illustrated in Fig. 1,1n operative position. Fig. 5, is asectional View showing the slide illustrated in Fig. 3, in position.

My invention is especially designed to be used in connection with theWheeler & Wil

son sewing machines, but-it can be applied to other machines with thesame advantageous results. I I A indicates a wide slide, such as isgenerally used for rotaryshuttle machines. Attached to the under side ofthis slide is a spring B, preferably U-shaped and extending transversethe said slide- I This spring has its ends bent downwardl yas shown atb.

To place the slide in position insert the inner notched end a, of theslide under the inner end of the slide opening, and then press itdownward carrying the ends b, of the spring into engagement with theside walls of the slot, when the slide will snap in position in the slotor opening and be held by the frictional contact of the ends I), withthe said side walls of the slide openin The spring is sufficientlystrong to hold the slide firmly in position and prevent it from anymovement by p & Wilsonmachines, of first removing a block and thenforcing the slide endwise, as now required.

In Fig. 3, the narrow slide is used for reciprocating shuttle machinesand extends across the bed of the machine, and is provided at its frontend with a lip on, which catches under the bed of the machine, and itsrear end with a spring 0 where it will be out of the way of the shuttle,and which catches under the throat platefor holding the said slide inposition.

While I show both ends of the spring acting as a spring, it will bereadily understood that one end may be rigid ora stop substitutedtherefor; while the other end forms a spring. I prefer to use the doublespring however as giving. the best results.

Having thus described my invention, what I claim, and desire to securebyLetters Patent,

slide-way, substantially as shown and described.

2. A slide for sewing machines having a spring secured to and extendingacross the under face thereof, the free ends of said spring havingholding lips at opposite edges of the slide, substantially as specified.

3. A slide for sewing machines having a U-shaped spring secured to theunder side thereof, the free ends of said spring extending to oppositeedges of the slide and having depending holding lips, substantially asspecified. I

In testimony whereof I affix my signature in presence of two witnesses.
